Don't understand it, my two sets of chickens (9 total) have not laid for over two months. Both sets have different birth dates over six months apart. They are cooped together and get along, they do have a pecking order. None of my birds are older than 4 years. Feeding them 16% layer food with extra goodies (meal worms/boss/kale) every now and then. Now that it is winter, I throw them scratch daily for body heat at night. Does anyone have any good ideas? I had to go back to buying eggs at the local store. Definitely not as tasty, P.S. , my wife and I have named them so chicken and dumplings are out of the picture.
